Okay, point taken. Since there's no source for RADIUS without entangled UDP 
transport, the RadSec I-D should have a section that states which parts of 
2865 are irrelevant when using a TCP transport. I.e. the draft should define 
the subset that matches the fuzzy expression of "RADIUS *at all*".

I'll go through 2865 and list the spots.

On a side note, 2865 has other hard-wired assumptions that aren't incredibly 
valid today. Are we going to split hairs on every one of them? That would 
mean making an update to 2865 though. Take for example

2. Operation

[...] If the client is valid, the RADIUS server consults a database of users 
to find the user whose name matches the request. The user entry in the 
database contains a list of requirements which must be met to allow access 
for the user.  This always includes verification of the password, but can
also specify the client(s) or port(s) to which the user is allowed access.

Enter EAP-TLS. Where's the database? What password? 

I somehow wonder why the introduction of EAP-TLS went by silently without an 
outcry that 2865 is too narrowly specified to allow this, by being hardwired 
to a specific set of auth backends. Back then, an RFC updated 2865 for EAP, 
and that was it. The fuss argumentation would be and could have been in a 
similar direction like the one we have here. It's a matter of personal liking 
or disliking a specific update I guess.
